Thanks to T-Mobile's innovative HotSpot@Home technology, the slick BlackBerry Pearl 8120 lets you make VoIP calls over Wi-Fi. The voice-over-Wi-Fi feature improves reception in locations where cell signals are weak. In our tests the technology (called Unlicensed Mobile Access, or UMA) worked very well, and the call quality was excellent.
The T-Mobile 8120 is less attractive than other versions of the Pearl, in part because of its drab gray exterior. The BlackBerry OS interface is a bit cluttered, as well. Aesthetics aside, the Pearl 8120 comes with a few productivity applications (such as a voice-command app and a Microsoft Office document viewer), along with some games. The Pearl 8120 also has superb battery life, with 10 hours of talk time.
